Clip-on handlebar extensions are great for turning your road bike aero. These T3 Plus bars from Profile are perfect for getting started on the aero path. They bolt on either side of your stem, and are tilt and length adjustable.
The elbow pads can be secured in a variety of positions â" make sure it's comfortable first before fine tuning. On the bike we found them sturdy enough (remember to tighten all the bolts), although care should be taken over bumps as clip-ons will always move.
The position offered is high compared with an integrated base bar and extension, which is all right to start with but you might want to experiment with lowering your stem once you're used to them.
